Be it digital UV, screen, or offset printing, each process is unique, and delivers high quality finishing across a variety of substrates. The decision of choosing the right process will primarily depend upon the material used and the finishing requirements. Of course, each one requires its own set-up of equipment and accessories. For purchasing second hand offset printing machines of international brands, one may get in touch with Printoholic, a leading importer & dealer of presses.

Digital UV (Ultraviolet)

This is an environment-friendly process, which involves the use of UV lighting for drying up the UV ink on the material. UV ink reacts instantly to UV light, thereby quickening the drying process. The end result is vibrant color on the material that is resistant to scratch and abrasion. Further, the UV ink is durable too. This procedure can be applied on practically any type of substrate.

Screen

This is the ideal procedure to be followed if printing needs to be carried out on cloth, plastic, glass, or metal. It involves the use of a screen/mesh to transfer the ink and imprint the required images onto the material. On applying pressure to the mesh, the ink is forced to be transferred to the surface. In case of multiple colors, various layers of mesh are used to enable colors to be printed separately. Post curing, the ink remains adhered to the material, thereby rendering it a long-lasting functionality. This method is ideal for simple designs and bulk quantities.

Offset

This procedure is widely used for producing magazines, flyers, brochures, and other visual communication materials. It consists of an assembly line, which has multiple printers in a row, through which the pages are passed for printing various colors. The good part is that the ink does not get disheveled even if the page is folded. It makes use of ink instead of solvents, and can process all formats, be it small, medium, or large.

When it comes to printing, the market has significantly changed over the past so many years. Earlier printing books, brochures, broadsheets, newspapers and other printed material are carried out via white-glove process. But our hearty thanks to Johannes Gutenberg’s for giving birth to movable printing machines back in 1439. Since then the printing process has been revolutionized immensely and has been widely used all across Europe and America. The movable type of printing comes with the greater advantage of faster printing of books which in turn allowed people to get in tune with the worldly knowledge and education.

Due to incessant technological advancements and up-gradations, printing has come a long way. Books and other printable commodities can now be produced in bulk in a very short span of time while maintaining the quality of printing. There are now a wide range of printing processes publishers can choose from. Let’s go though some of the most popular printing methods used today.

Offset – The full name of this Printing process is offset lithography. Offset printing technology is the most commonly used printing technique on the market, appropriate and fast for printing on paper, cardboard, plastic and other flat materials. Offset is widely used for printing books, newspaper, brochures, broadsheets, stationery, packaging, etc.

Flexography – In flexography flexible (generally rubber) printing plate is used, which stretches the range of substrates that can be printed on. Material such as Plastics, metals, cellophane and other materials can be easily printed on. Flexo technology is generally used for packaging and labels and to a less widely for printing newspapers.

Digital printing – Digital printing is a recent developed technique where printing is done using digital image through a range of media.

Different variants of printing technologies such as inkjet and xerography are also referred to as digital printing. These are the newest processes and as such, they are gradually replacing other traditional processes. They also offer new opportunities such as variable data printing, in which each printed copy is entirely different from the previous one.

Screen printing – Screen printing is carried out by using a mesh to transfer ink onto a substrate, leaving the areas made impenetrable to the ink by a blocking stencil.

This printing technique can be done on a wide range of materials and the printing surface does not necessarily have to be perfectly flat. Printing t-shirts or glass surfaces or on wood are some of the examples.

Rotogravure – Also known as gravure, is a type of intaglio printing process, this is a technique in which an image is engraved onto a printing cylinder. That cylinder is inked like offset printing and flexography, it uses a rotary printing press. The ink engraved onto the cylinder is subsequently transfers to the paper.

Feeder/ Loader: This section of the unit comes outfitted with suction heads that transport sheet material from the pile to the machine in feed.

In-Feed: This section is responsible for controlling the movement & transportation of each individual sheet. With the help of mechanical or dynamic registration, the in-feed also registers the sheet material to the cutting tools.

Stripping Section: The stripping section functions as a waste removal unit, which aids in getting rid of internal waste, side, and rear trims. The two tools, upper and lower, work together to remove the excess material.

In the offset printing industry, delay accounts for almost 30%, which implies a loss of about one –third of the press time. There are several factors that may trigger a delay, but before discussing that, first, let’s have a look, what exactly constitutes a delay in this industry? It does not comprise makeready or dead time between tasks; rather, it refers to those times when production needs to be stopped for factors that do not pertain to the normal operation of the press. For instance, inadequate maintenance of the machine may result in a mechanical issue, which, in turn, may put the production on hold. Listed below are the most common reasons and their corresponding fixes for delays on new & Used Offset Printing Machines:

Used Offset Printing Machines

Web break on start-up

This may occur for several reasons, including, usage of too much or too little water, high blanket, excessive or inadequate tension, and many more. The resolution is simple – provide training to the pressmen so that there is little scope of human error.

Running Web Breaks

This is the second biggest reason behind a delay. While some may opine that running web breaks are normal delays and there’s not much that can be done in this aspect, the truth is that these delays can be prevented by providing training to the crew on the subjects of adjusting the infeed according to the paper density & quality, keeping a tab on the tension, and much more.

Mechanical Issue due to Inadequate Maintenance

Now, this is the cause of a delay for any machine. It is a known fact that proper preventive maintenance helps in increasing the life of the machine as well as prevents from frequent breakdown. A regular lubrication of an Adast Printing Machine or any other printing press of a reputed brand can go a long way in preventing unnecessary delays.

One should always remember that it’s not just about finding a fix to the problem, but it is essential to identify the root cause of the delay, so that it does not occur again.

While buying new or Used offset Printing Machines in India, it is important that one is aware of the essential terminologies used in this industry. An understanding of these terms can be of immense help at the time of dealing with an Offset Printing Machines Importer in India. Here’s a sneak peek:

Signature

In simple terms, a signature refers to the single printed product that comes out from a press. It may consist of several pages. Similar to handwritten signatures, each signature generated from the offset press is also different from one another and each one of them bears a distinct unit configuration. Those aspiring to purchase Second Hand Offset Printing Machines in India may contact Printoholic, a reputed Offset Press Machines Importer and Dealer in India. In fact, it is the Biggest Offset Printing Machines Dealer in India.

Impression

When Offset Printing Machines complete one full revolution, they are said to complete an impression. It is important to note here that one impression may comprise several signatures. It is always advisable to generate as many signatures as possible in a single impression, as this will ensure saving of time and resources.

Press Check

Similar to a quality check, which is carried out in manufacturing activities, a press check involves checking and approval of the signature by the customer. Generally, a customer assesses whether the finished product conforms to the requirements of color, fold, and other attributes.

Makeready

This implies the time taken to set up the machine for producing the required task. Thanks to technological advancements, today, offset press machines come outfitted with presets, thus offering shorter makeready times. Of course, mounting the plates and paper will need some time.

These are only a few of the basic terms used by pressmen and salesmen.

Here’s some more information on Things to Remember While Working on an Offset Printing Press.
